Foam latex...

Within this post the use of foam latex will be spoken about. Foam latex is a light, flexible material that allows air through it and is easily painted.

To mix up the foam latex you will need to use;

• 300g of foam base (latex)
• 60g of  foaming agent (20% of base)
• 30g of curing agent (10% of base)
• Gelling agent (10%-15% of base)

The gelling agent is affected by temperature, the warmer the surroundings are the less of the gelling agent and the colder the surrounding temperature is the more gelling agent you use.

An electric whisk is used to mix the foam latex. Put it on the maximum speed for 4 minutes after turn down to the lowest setting and refine for 6 minutes. After this the gelling agent is evenly distributed through out for 2 minutes (using a syringe helps). Using to much of the gelling agent will cause the foam latex to set fast. When i made the foam latex the room was 24 degrees (warm) so i used 37-28 of the gelling agent.  

Once the foam latex has finished being mixed promptly place some of it into the centre of the mould spreading out all over the mould making sure to get into all the details once this is done put a little more into the centre. Once this has been done get the cast and press it down into the mould like the images show below.
